OF NEW YORK, N. Y.

TRANSOM-MOVER.

To all whom it may concern:

Be it known that I, CLARENCE T. Romans, of the city, county, and Stateof New York, have invented a new and useful Improvement inTransom-lvlovers, of which the following is a full, clear, and exactdescription.

My invention relates to in'iprovements in transom movers and devices foropening and closing transoms or ventilators, and is especially intendedto provide a device which is contained within the casing of a door sothat no part of the mechanism is visible except the wheel or handlewhich operates the device. f

Another object of my invention is to produce an opener for transomswhich will be self-locking in its operation, so that when a transom orventilator is opened it will antomatically look so that it will beimpossible to move or close the transom by force or pressure applieddirectly thereto.

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which similar reference characters indicatecorresponding parts in all the views.

Figure 1 is a view of my device as applied to a door frame. Fig. 2 is aside vlew of the same within the door frame, and Fig. 3 is a top view ofthe lower part of the device showing the self-locking arrangement.

It is intended that my device shall be supported within a door frame sothat no part of it will be visible except the handle operating the same.In the drawings I have illustrated it as supported in a door frame 10and intended to open the transom 11. The transom 11 is illustrated inthe drawings as pivotally supported on the rod 12. It is understood,however, that the transom can be swung also when supported in the middleor at the top. In order to rotate the rod 12 and open the transom, Iprovide a pinion or segment of a pinion 13 Which is adapted to engage arack 14, this rack being supported and held in position by the arm 15which is secured to the door frame, and is bent around and in as shownat 15 to form a guide for the rack 14.

Secured to the lower end of the rack 14 is a rod 16 which carries at itslower end another rack 17 which engages in turn a pinion 18. This pinion18 is rigidly secured to a sleeve 19 which is supported on the doorframe by the bracket 22 having arms 23- and 23". The sleeve is sosupport- Specification of Letters Patent.

cd in these arms 23 and 23" that it can rotate, and can also be movedlongitudinally. \Vithin the sleeve I provide a shaft 20 adapted torotate therein and also he moved longitudinally therethrough. This shaft20 extends through the sleeve and is supported at its inner end by thearm 23, and is held in place against lateral movement by the nut 20. Therod 20 carries a spring 24 between the arms 23 and 22 and this spring 24abuts at one end against the arm 23 and at the other end against the endof the sleeve 19.

In order that the device may be self lookng, I provide a fixed rack 25which is adacent to the movable rack 17, and adapted to engage thepinion 18. In order that the pinion 18 may be moved in and out ofengagement with the rack 25, I provide an opening in the sleeve 19 nearits outer end, which opening has on its sides cam surfaces which areadapted to engage the screw carried upon the shaft 20. It is apparent,therefore, that when the shaft 20 is rotated by means of the Wheelhandle 21, the screw or pin 27 will, by reason of the cam surfaces ofthe opening 26, move the sleeve 19 in, throwing the pinion 18 out ofcontact with the rack 25, and allow of an up and down movement in themovable rack 17, thereby operating upon the segment 13 and openin orclosing the transom. On the other han when the rotating pressure isremoved from the wheel 21, the spring 24 ressing against the sleeve 19will move the s eeve 19 and the pinion 18 with it out, so that thepinion 18 will lock on the fixed rack 25, thereby locking the transom inwhatever position it may be, and making it impossible to either 0 en orclose it without turning the wheel han le 21.

I claim 1. A transom mover comprising a bracket secured to a door frame,a spring pressed sleeve having cam surfaces thereon su ported on thebracket, a pinion rigid secured to the sleeve, a fixed and a movab erack normally engaged by the pinion, a shaft movably sup orted in thesieve, means for rotating the s aft, a pin ecured to the shaft andcooperating with the cam surfaces on the sleeve, whereby when the shaftis rotated the sleeve will move longitudinall to carry the pinion out ofengagement witfi the fixed rack and will then rotate with the shaft, anda second movable rack connected to the first movable rack and engaging agear segment rigidly supported on a transom to swing the same whenturned.

2. A transom mover comprising the gear segment secured to a transom toswing the same when turned, a movable rack engaging the gear segment, abracket secured to a door frame, a second movable rack connect ed to thefirst movable rack, a fixed rack supported on the bracket, a pinionnormally engaging the second movable rack and the fixed rack and adaptedto move in and out of engagement with the fixed rack, and means formoving the pinion out of engage ment with the fixed rack and adapted torotate the same.

3. In a transom mover a spring pressed sleeve supported on a door frame,a pinion rigidly supported on said sleeve, a fixed and a movable racknormally engaged by the pinion, means for moving the sleeve to move thepinion out of engagement with the fixed rack said means being alsoadapted to rotate said pinion, and operative connection between themovable rack and a transom.

4. In a transom mover, a rotatable sleeve supported on a door frame andmovable longitudinally, a pinion rigidly supported on the sleeve, ashaft supported within the sleeve, means for rotating the shaft, a fixedand a movable rack normally engaged by the pinion, means on the shaft;engaging the sleeve to rotate said sleeve and move it longitudinally inrelation to the shaft when the latter is rotated, and operativeconnection between the movable rack and a transom.

5. In a transom mover, a spring pressed sleeve supported so that it willrotate and move longitudinally in its bearings, a pinion rigidlysupported on the sleeve, a fixed and a movable rack normally engaged bythe pinion, means supported in the sleeve to rotate the sleeve and moveit longitudinally, and operative connection between the movable rack anda transom.

(l. A transom mover comprising a sliding rack supported on a door frame,a fixed rack adjacent to the sliding rack, a rotatable pinion movablelongitudinally on its axis to engage the sliding rack and the fixedrack, a handle operatively connected with the pinion, and operativeconnection between the sliding rack and a transom.
